SafetyNet Step 2:
Use filterware

The goal of filterware (also called filtering
software, parental control software or blocking
software) is to give parents technical tools to block Web sites, newsgroups, e-mail and
chat that could be harmful to children. While approaches vary, most filterware contains
combinations of the same basic two components: words that trigger the blockage of a site
and a list of sites to be blocked. Neither method works all the time, but a combination of
the two screens out most objectionable matter. KidShield research shows that the only way
to block all objectionable matter is to use filterware that limits access to sites that
have been pre-approved. Sadly, since preapproved lists are so small compared to the vast
amount of web sites, such a move severely limits your childs access to the Web and
removes much of its potential good as well as its harm.

Filterware alone does not provide sufficient protection for
online children. Children still can stray  or be lured  into trouble. To
maximize your childrens safety, you must augment the software you choose with the
remaining guidelines governing Internet use. Do not rely exclusively on software to create
your family's SafetyNet.
